ath9k not working on resume

[David Huggins-Daines]

After suspending and resuming my eeepc 1005ha, the wireless no longer works. When I run "iwlist wlan0 scan" I get:

dhuggins@bluesy:~$ iwlist wlan0 scan
wlan0 Failed to read scan data : Resource temporarily unavailable

Removing and re-inserting the ath9k module makes it work again - scanning works and I can connect to the network.

Is there some way to force this module to be unloaded and reloaded on suspend/resume? Or, I suppose, it would be even better if the driver supported suspend and resume :-)
